Revelation 8 is the eighth chapter of the Book of Revelation or the Apocalypse of John in the New Testament of the Christian Bible. The book is traditionally attributed to John the Apostle, but the precise identity of the author remains a point of academic debate.
In verse 1, the opening of the seventh seal concludes a section beginning in chapter 6 which records the opening of the "Seven Seals". Verses 2-13 and chapters 9 to 11 contain an account relating to the sounding of the "Seven Trumpets". In chapter 8, the first four angels' trumpets are sounded.
